Over the years, the most useful FFT software I've had,
is the (fairly simple) FFT analyzer in Audition/CEP.
It's big plus is the ability to use the Audition/CEP
audio editor to select portions of real-world waveforms,
and to use the wave generation and modification features
to create waves for use in analysis and testing.


I am sure this is an useful tool, but without windowing
the data, any semblance to reasonable analysis is a house
built on sand.


So you think that the FFT analysis tool in CEP doesn't do windowing?????

I note in your provided link to work you
have done that you use Blackman exclusively. This is at
least a good first pass to achieving an analysis, but any
variety of work is going to be more demanding (the
Blackman window has its limitations), otherwise it is
like looking through glasses smeared with Vaseline.


So you think that Spectra doesn't provide options for windowing and/or that
I have no idea what effect they have on actual results????
